Here’s one frame from my embedded iteration. I wrote a helper function to draw each shape (an astroid) and then added a bit of randomness to generate the different greys and shades of red. If you look at it in openprocessing, you can see it “twinkling”.

I made a wallpaper design of stars, circles and triangles, sometimes overlapped and sometimes not, sometimes with borders and sometimes without. The colors change as they go across and down the screen, with a subtle amount of randomness thrown in. I was kind of going for an early 90’s/Trapper Keeper/Lisa Frank feel here.
